South Windsor is a residential suburb within the City of Hawkesbury, located approximately 60 kilometres north-west of Sydney's CBD in New South Wales. Its SEIFA IRSAD score of 1001 sits almost exactly at the national mean of 1000, placing it in decile 7 of 10 nationally and at the 57th percentile within New South Wales. That reading puts the suburb in the broadly advantaged band, though only marginally above the midpoint, which means the socioeconomic profile here is genuinely mixed rather than strongly skewed in either direction. Investors should treat this as a suburb where individual listing quality matters more than the postcode frame alone.
ABS 2021 IRSAD release. Score 1001 (national mean = 1000).
A SEIFA IRSAD score of 1001 tells PropertyRanker that South Windsor sits in a zone of moderate economic strength. The suburb is not a high-disadvantage area, but it is not a high-advantage enclave either. Within PropertyRanker's model, this reading feeds three of the twelve scoring criteria: economic_strength receives a neutral-to-mild positive signal, hazard_risk is flagged for further review because parts of the Hawkesbury floodplain are known to affect properties in and around this postcode, and entry_point_risk is assessed as moderate given the suburb's position at the outer edge of Greater Western Sydney's commuter belt. The proximity to RAAF Base Richmond is a structural demand factor that has historically supported rental occupancy in the corridor, particularly for short-to-medium term tenancies. Windsor railway station provides a rail connection to Sydney, though the journey time to the CBD is long and car dependency remains high for most residents. The suburb's population of roughly 6,000 includes a notable proportion of social housing, which contributes to the mixed socioeconomic profile the SEIFA score reflects. On strategy fit, the distance from the CBD and the moderate price point relative to inner-ring Sydney suggest this suburb is more likely to align with a Balanced or High Yield strategy (gross yield anchors around 5 to 6 percent) than a Capital Growth strategy, though that assessment depends entirely on what a specific listing is priced at and what comparable rents are doing at the time of analysis. A Regional strategy anchor of around 7 percent gross yield is possible on some stock types but would need to be confirmed against current vacancy and rental data.
South Windsor NSW 2756 recorded a median house price of $968,000 with annual capital growth of 9.69% over the 12 months to May 2026, according to yourinvestmentpropertymag.com.au sourcing CoreLogic data, with 103 house sales transacted and an average of just 16 days on market. propertyvalue.com.au (Cotality) reported 87 house sales with a median of $895,000, up 8.9% annually, and an average vendor discount of -4.1%, while htag.com.au flagged a vacancy rate of just 0.64% and active stock of only 0.25%, pointing to a tight supply and strong demand environment across the suburb.

All three signals point to a seller's market: vacancy is very low at 0.64%, days on market have compressed to 16-27 days, and vendor discounts of -4.1% reflect vendors holding firm amid strong demand.

PropertyRanker scores any Australian property against 12 criteria across three pillars: Growth, Cashflow, and Risk. SEIFA is a primary signal for economic strength and a supporting one for entry-price risk. It also informs the crime side of hazard risk, though physical overlays like flood, bushfire and coastal exposure, and recorded crime data where available, take priority there. The decile of 7 shown above gives a listing in South Windsor a stronger starting line on economic strength than the national median postcode, and a softer one on entry-price risk, since more advantaged postcodes usually carry higher entry prices.
On top of that, PropertyRanker chooses one of four strategies (Balanced, Growth, Yield, Regional) and applies a per-strategy yield anchor. The anchors are 3.5% for Growth, 5% for Balanced, 6% for Yield, and 7% for Regional. A postcode at this level of relative advantage tends to suit the Growth (3.5% anchor) and Balanced (5% anchor) strategies more readily than Yield (6%) or Regional (7%), because a higher entry price compresses the gross yield a listing can reach without a specific value-add.
Read the scoring guide for the full criteria list and how the verdict thresholds work.
The SEIFA reading cannot see flood overlay status, and this is the single most important item to verify for any South Windsor listing. Parts of the suburb sit within or near the Hawkesbury River floodplain, and Hawkesbury Council flood mapping should be checked against the specific lot before any other analysis proceeds. Beyond flood risk, investors should confirm whether the property is in a social housing cluster or a predominantly owner-occupier street, as this affects both rental demand quality and long-term capital trajectory. Build year and construction type matter here given the age range of the housing stock. Strata properties require a review of body corporate financials and any outstanding levies. Vacancy conditions in postcode 2756 can shift with defence posting cycles at RAAF Base Richmond, so current SQM vacancy data is a more reliable guide than historical averages. Score the specific listing in PropertyRanker to get a verdict that accounts for what this postcode-level SEIFA reading cannot see, including current SQM vacancy, body corporate health, flood and overlay status, and pricing against recent comparable sales.
South Windsor's SEIFA IRSAD score of 1001 places it almost exactly at the national mean, signalling a mixed but not disadvantaged socioeconomic profile. That reading is one of twelve signals PropertyRanker uses, and it does not by itself make the suburb a strong or weak investment case. The quality of a specific listing, its flood overlay status, and its pricing against recent comparable sales in postcode 2756 will determine whether a particular property scores well or poorly within this postcode frame.
Given the suburb's location roughly 60 kilometres from Sydney's CBD and its moderate SEIFA profile, the Balanced strategy (gross yield anchor around 5 percent) or the High Yield strategy (around 6 percent) are the most plausible starting points for analysis. A Capital Growth strategy, which anchors around 3.5 percent gross yield, would require strong evidence of price appreciation drivers that are not clearly present at this distance from the CBD. Score the specific listing in PropertyRanker to see which strategy the full twelve-signal model supports for that property.
Flood exposure is the primary risk to verify, as parts of the suburb and the broader Hawkesbury floodplain are known to be affected, and this directly influences PropertyRanker's hazard_risk signal. A notable proportion of social housing in the suburb contributes to the mixed socioeconomic profile reflected in the SEIFA score, which can affect rental demand consistency and resale liquidity on certain streets. Commute time to Sydney is long, which limits the depth of the owner-occupier buyer pool and can slow capital growth relative to closer suburbs.
Proximity to RAAF Base Richmond has historically supported demand for short-to-medium term rentals in the Windsor and Richmond corridor, as defence personnel postings create a recurring tenant pool. This is a structural demand factor that PropertyRanker's model does not capture directly from SEIFA alone, so current SQM vacancy data for postcode 2756 should be checked to confirm whether that demand is active at the time of analysis. Score the specific listing in PropertyRanker for a vacancy-adjusted verdict.
PropertyRanker applies twelve scoring signals to each listing, with SEIFA IRSAD (score 1001, decile 7, 57th percentile in NSW) feeding the economic_strength, hazard_risk, and entry_point_risk criteria at the macro level. The remaining signals draw on listing-level data including current SQM vacancy for postcode 2756, flood and planning overlay status, body corporate health for strata properties, and pricing against recent comparable sales. The SEIFA reading sets the postcode context, but the listing-level signals determine the final score.
